Using a PSU in a external box... on /off?

[Mr.Guvernment]

Hey all

i am building a cube for my water cooling stuff for the pump /rad/fans

and i wanted to use an old pwoer supply i have as the power source - question - how can i make the power supply simply turn on and off with the switch or by plugging it into the wall and not being connected to a mother board.?

If you short the green ATX wire with one of the grounds (blacks) your PSU will be permanently on. You could connect a switch to it, so u could just switch it on and off, sort of AT PSU
